Sure she did. Are you going to go against the Director of the Paul Revere House... but that would be silly...
"Revere's assignment that night was to go to Lexington to warn Samuel Adams and John Hancock that British troops were moving in that direction from Boston," explained Kristin Peszka, director of interpretation and visitor's services at the Paul Revere House, which Palin visited Thursday.
It was an extremely complicated situation which she sort of regurgitated in a garbled way," Boston University's Brendan McConville said.
"He didn't warn the British," said James Giblin, author of "The Many Rides of Paul Revere." "That's her most obvious blooper."
To the source: In a 1798 letter, Revere wrote that after being captured by British officers during the midnight ride, he told them "there would be five hundred Americans there in a short time for I had alarmed the Country all the way up." Does that mean he warned the British? Not exactly.
"He wasn't really warning the British when he was a captive," said "Rides of Paul Revere" author Giblin. "He was just, in a way, boasting about the capabilities of Americans. 'You don't know what you're going to be up against,' etc. He was playing the patriot even there. He did maybe inflate the American strength, but that was to throw the British off guard. He was propagandizing, really."
